REPAIR
Tools and repair accessories
With the following tools, all described disassembly and repair work can be done:
Repair work without disassembling the machine
Without disassembling the machine, you can clean, replace or repair the following parts:
• Water tank (pos. 6)
• Capsule holder (pos. 17)
• Injector plate (pos. 19)
• Drip tray (pos. 13) and drip grid (pos. 14)
Cleaning or replacing injector plate, deblocking of injector
Solid residues in the water circuit can block the injector completely. An example is the
development of calcium particles if the machine is not descaled periodically. Therefore
this error appears during descaling frequently.
A pin-torx screw
head looks like this:

5. Close locking handle (pos. 2).
6. Release latch by pressing a suitable pin (dia. 1.8 mm max. e.g. a paper clip)
through hole and remove injector plate (pos. 19) by pulling it down.
7. Examine upper side of injector plate (pos. 19).
8. Clean interior space of sealing ring with a toothpick etc.
Danger of injury -
sharp pointed
injector!
The extraction
head is adjusted to a
specific injector plate
(pos. 19). Therefore do
not mix up different
injector plates acciden-
